A growing consensus argues that minimum parking requirements (MPRs) make housing more expensive. This paper examines two claims from this discussion: (1) that MPRs discourage the construction of small units; (2) that the costs of building required parking are "passed on" to buyers and renters in the form of higher prices and rents. However, the mechanisms behind these two effects have never been made explicit in the literature. This paper proposes, for each claim, a plausible mechanism relying on the specific choices of housing suppliers and consumers. We propose that MPRs discourage small units because they eliminate the most profitable floorspace/parking bundle to supply to relatively lower-income households. We propose that parking costs may be passed on by reducing the supply of housing on offer at a given price.

最低停车要求如何使住房更昂贵

越来越多的共识认为，最低停车要求（MPR）使住房更加昂贵。本文考察了这次讨论的两个主张：（1）MPR不鼓励建造小型单元；（2）所需停车的建筑成本以较高的价格和租金形式“转移”给购房者和租房者。但是，这两种作用背后的机制在文献中从未明确。本文针对每项主张提出了一种可行的机制，该机制依赖于住房供应商和消费者的特定选择。我们建议MPR劝阻小型单位，因为它们消除了提供给相对较低收入家庭的最有利可图的占地面积/停车位。我们建议可以通过减少给定价格的住房供应量来转移停车成本。
